Oh, a cute idea and space saver. Definitely worth clicking through for more details.
You can hang your plants from curtain rods, hooks in the ceiling, or just about anywhere that gets plenty of light. I hung my herbs over the sink in my kitchen so they would be within easy reach while I was cooking. So far I haven’t had any problems with leaking, but you may want to avoid hanging your plants over hardwood floors or other surfaces that don’t take kindly to being dripped on.
